Online standardize this thing basically can not see it. Concrete road expansion joints false seam, not cut in the end. 1, less than 10 ℃ temperature difference between day and night construction, the longest time shall not exceed 24h; there are dowel contraction joints kerf depth should be 1/3 ~ 1/4 thickness, the most shallow of not less than 70mm; no dowel shrink seam kerf depth should be 1/4 to 1/5 thickness, shall not be less than the lightest 60mm. 2, the longitudinal rod has been inserted false contraction joints, slit depth of not less than 1/3 ~ 1/4 thickness, the most shallow lancing depth of not less than 70mm, vertical and horizontal expansion joint should simultaneously slit. 3, contraction joints kerf width should be controlled at 4 ~ 6mm, while the blade slit swaying should not exceed 2mm. Can be cut with a thin blade to the required depth, and then use 6-8mm thick squat squat sheet or laminated sheet groove widening caulk, caulking groove depth is preferably 25 ~ 30mm, width appropriate for 7 ~ 10mm.
